Bring the liquid to a brisk boil.
Reduce heat and simmer gently until the broth is reduced and a glaze forms at the bottom.

Add sherry, soy sauce, and cayenne.
Simmer for 20 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Browning from frying builds savory flavor, and the meat gives the broth its body.
- Flour
- Coats the beef for browning and, mixed with butter, thickens the finished soup.
- Fried onions
- Caramelized sweetness and savory depth form the base flavor of the broth.
- Butter
- Mixed with flour, it enriches the soup and thickens it smoothly.
- Sherry
- Adds acidity and aroma that brighten the rich broth.
The step that matters
Thicken with butter and flour mixed smoothly. Flour added directly to hot liquid clumps. Mixing it smoothly with butter first lets the starch disperse evenly, so the soup thickens without lumps.
Swap the onion
